DELIVERY MECHANISM FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 383,799, dated May 291888. Application filed November 9, 1887. Serial No. 254.669. (Nomodel.)

To all whom it may concern: 1

Be it known that I, LUTHER 0. (Bowen,

a citizen of the United States, residing at Brooklyn, county of Kings,and State of New York, have invented certain new and useful Improvementsin Delivery Mechanism for Printing-Machines, fully described andrepresented in the following specification and the accompanyingdrawings, forming a part of the same.

This invention relates to a delivery mechanism which is especiallydesigned to be used in connection with a webprinting mechanism whichprints upon a plurality of webs or upon a wide web which is splitlongitudinally into a plurality of narrower webs after being printed, itbeing the object of the invention to produce a simplified form ofdelivery apparatus by which a plurality of webs thus printed can bedelivered'in products of various sizes or volumesas, for example, inproducts composed of one, two, or four sheets.

To this end the invention consists, priucipally, in a novel arrangementof a plurality of 2 5 longitudinal folders with relation to the otherparts of the mechanism whereby the full capacity of the printingmechanism can be utilized in producing single-sheet productswithoutduplicating the entire delivery mechanism.

0 The invention also embraces certain other novel features andcombinations. of parts, all

of which will be hereinafter fully explained, and particularly pointedout in the claims.

As a full understanding of the invention can best be given by anillustration and a detailed description of an organized deliverymechanism embodying the. same, all preliminary description will beomitted and a full description given, reference being had to the accompanying drawings, in which- Figure 1 is an elevation (parts of theframework being broken away) of a delivery mechanism embodying theinvention, showing also a diagram of the principal parts of the printingmechanism. In this, as also in the remaining views of the drawings, thegearing and many of the minor details of the mechanism are omitted, assuch parts can readily be supplied by any ordinarily-skillful mechanic,and if shown would only tend to create confusion. Fig. 2 is a plan viewof the same. Fig. 3 is an end elevation, partly in section, looking fromthe left of Figs. 1 and 2. Fig. 4 is an inside view of one of thelongitudinal folders. Fig. 5 is an edge view of the same, looking fromthe left of Fig. 4. Fig. 6 is a perspective view of the same. Figs. 7,8, and 9 are views similar to Figs. 1, 2, and 3, illustrating a modifiedconstruction of one of the longitudinal folders, which will behereinafter referred to. Figs. 10, 11, and 12 are also similar viewsillustrating another change or modification. Fig. 13 is a front oroutside view of the folder detached. Fig. 14. is an edge view lookingfrom the right of Fig. 13. Fig. 15 is a horizontal section taken on theline 15 of Fig. 14. Fig. 16 is an enlarged end view of the cutting,folding, and associating cylinders. Fig. 17 is a partial plan view ofthe same. Fig. 18 is a section taken on the line 18 of Fig. 17, showingthe parts in a different position. Figs. 18 and 18" show a detail whichwill be hereinafter explained. Figs. 19 to 26 are views showing thedifferent-sized products. Figs. 27, 28, and 29 are views similar toFigs. 7, 8, and 9, illustrating an organization in which two fold ers ofthe same form are used.

Referring tosaid drawings, it is to be understood that the printingmechanism is of substantially the ordinary form, consisting of 8formcylinders A, impression-cylindersB, and inking mechanisms,(represented by the rolls and cylinders 0,) all of which are arranged inthe usual manner and are of sufiicient length to capacitate the machineto operate upon a double-width web.

The web D is led from a roll, and after passing between the first formand impression cylinders to be printed upon one side is led be tween thesecond form and impression cylinders to be printed upon its other side,and then passes over a roll, 50, where it is operated upon by a slitter,49, and split into two longitudinal sections or narrow webs, d, whichnarrow webs are then led to the delivery mechanism.

The delivery mechanism, as herein illustrated, consists of a web-turningor turning and associating mechanism of ordinary form, composed of twoweb turners, 47', two longitudinal folders, G H, a transverse cutting,folding, and associating mechanism composed of two cylinders, 45 4.6,and a sheet-piling mechanism composed of a rotary S-shaped fly, 53, anda series of slowly-moving belts or tapes, 54.

The web-turners 47, composing the web turning and associating mechanism,are arranged obliquely across the paths of the webs d, so that when thetwo webs are led around their respective turners they will be turned atright angles to their previous course and brought one directly beneaththe other. The web-turners 47 are adjustable, so that they can beshifted to secure the proper adjustment.

The folder G is of substantially the form and construction illustratedand described in United States Letters Patent N 0. 331,280, heretoforegranted to me. It may, however, be of any other suitable form. Theexternal turners 20, and also the fold-laying rolls 23, which co-operatewith this folder, are, however, for a purpose that will presentlyappear, made slightly longer than in the construction shown in saidLetters Patent.

The folder H is located upon the outside of the frame-work of themachine in a position substantially at the side of the folder G. Thisfolder (see Figs. 4, 5, and 6) consists of aninternal plate, h, arrangedin a slightly-inclined position and turned inward at its lower end, soas to provide an internal guide, 9, to act upon one half the width ofthe web, and is cut away on one side, so as to form an oblique internalguide, 8, for the other half of the width of the web. The internal guide9 is, as will be observed, arranged at right angles to the travel of theweb. This plate It is supported at its base upon arms 18, which areloosely mounted upon the bushings of the shaft of a roll, 19, located atthe base of the plate, and is adjustably supported at its lower end bymeans ofa rod, 17, extending from the framework of the machine. plate Itis an external plate, 9, which extends along the oblique guiding-edge 8of the plate h .and inward, and is formed at its lower edge to providean external turner, 10, which acts to turn the half of the web whichpasses over the guidingedge 8 inward and double it over onto the otherhalf of the web, as indicated in Fig. 1. The plate 9 is also adj ustablysupported by rods 16, extending from the framework of the machine.

The two folders G H are positioned with relation to each other so thatthe two webs, after being longitudinally folded, will, as they passbetween the fold-laying rolls 23, overlap with the folded edge of eachprojecting beyond the unfolded edge of the other. Located between thefolder H and the fold-laying rolls 23 is a guide-roll, 15, over whichthe web folded by the folderH is led as it passes to the rolls 23.

The folder H is adjustable to enable it to properly fold webs which varysomewhat in width, to permit which the arms 18 are adjustable upon theirsupporting-bushings, while the openings in the frame-work which receiveresponding movement of the webs.

Cooperating with the The cutting, folding, and associating mechanism iscomposed of two cylinders, 45 46, and a pair of folding-rolls, 14, whichare equipped and operate upon the same general plan shown and describedin my prior Letters Patent, No. 317 ,740. The details of the equipmentof the cylinders 45 46 are, however, somewhat different from what isshown in said Letters Patent, and will be described.

The cylinder 46 (see Fig. 16) is of a circumference equal to the lengthof two of the sheets to be produced, and is provided at opposite pointswith two cutting-grooves, 2, and at the proper points between thesegrooves with a pair of rotary folding-blades, 4, which operate in theusual manner to fold the sheets from the cylinder intothe'bite of thefolding-rolls 14. The cylinder 46 is also provided with two sets ofsheet-holding pins, 3, which are located just in the rear of the'cuttinggrooves 2. These pins pass through openings in the periphery of thecylinder and are pivoted upon the ends of arms'extending fromrock-shafts 28, journaled in the heads of the cylinder and pro videdwith arms 29, having studs or bowls which are engaged by a stationarycam, 30, in such manner as to retract the pins at the proper times. Thepins are normally held in their protruded position by means of springs31, which act upon rods 32, which are pivoted to arms extending from theshafts 28 and pass through guides 33 upon the cylinder-head. In order tohold one set of the pins permanently retracted, which will sometimes benecessary, as will be hereinafter explain ed,the rod 32 of that set ofpins is provided with a latch, 34, which is arranged to engage with theguide 33, so as to hold the rod and prevent the spring 31 fromprotruding the pins. This latch forms no part of the present invention,as it is claimed in a companion application, filed November 10, 1887,Serial No. 254,765. It is also to be remarked that any other suitable orconvenient means may be employed for holding the one set of pinsretracted.

The cylinder 45 is of a circumference slightly less than one-half thecircumference of the cylinder 46, and is provided with a cuttingblade,5, of the ordinary form, which is arranged to co-operate with thegrooves 2 in such manner as to sever a sheet from each web at eachrevolution of the cylinder 45. This cylinder is also provided with oneset of impaling-pins, 6, which are pivoted upon arms extending from arock-shaft, 35, which is journaled in the heads of the cylinder and isprovided with an arm, 36, having a stud or bowl,

' 48, proje'ctingfrom the cylinder-head. The

proper movement of the switch 38is imparted from a crank-pin, 39, uponthe shaft of the cylinder 46, which is connected by a rod, 40, with anarm, 41, extending from the pivot of the switch 38.

It will sometimes be necessary, as will be hereinafter explained, tohold the pins 6 permanently retracted. To effect this, the rod 40 willbe disconnected from the crank-pin 39 and hookedonto a stationary stud,42, provided for that purpose. When the rod 40 is thus hooked onto thestud, the switch 38 will be held in a central position, (see dottedlines in Fig. 18,) so that the bowl of the arm 36 will be prevented frompassing to the inside of the guide 37, and the pins will, as aconsequence, remain retracted. The delivery mechanism thus organized iscapacitated by slightly different adjustments to deliver the fullcapacity of the printing-machine, either in the form of one, two, orfour sheet products, folded once longitudinally and once transversely,or three-fourths the full capacity of the printingmachine in productsconsisting of one full and one half-sheet or two full and twohalf-sheets,

folded to the same dimensions.

The operation of the mechanism in delivering these different products isas follows: If it is desired to utilize the full capacity of theprinting-machine in producing four-paged papersthat is to say,papersconsisting of one cylinder 46 will be rendered operative.

full sheetthe folders G H will both be used, the pins 6 of the cylinder45 will be permanently retracted, and both sets of pins of the Thefull-width web D will be used, and, after being printed, it will besplit and one of the webs d will be led around the inner one of theturners 47, and thence around the roll 22 to the longitudinal folder'G,and thence, after being longitudinally folded, to the cylinders 45 46.The other web d, instead of passing around the other turner 47, willpass directly forward over the roll 19 and downward over the folder H.As the web passes over the plate It, the inn'er half the web will beacted upon by the edge 10 of the plate 9 and turned inward around theoblique guiding-edge 8, so as to be laid over onto the other half of theweb, thus folding the web longitudinally. The web thus folded will thenbaled over the roll and .between the fold-laying rolls 23 to thecylinders 45 46.

It will be observed,as before stated,that the two folders G H are sopositioned that the two webs as they pass between the fold-laying rolls23 are overlapped, as indicated in Figs. 3 and 24. In this condition thetwo webs will pass into the bite of the cylinders 45 46,where theleading ends of the websare taken by one set of the pins 3 and carriedaround upon the cylinder 46 untilthe foldingblade 4 arrives in properposition to fold the sheets between the rolls 14, when the pins will beretracted and the blade operated to fold the sheets between the rolls.Just previous to this. the blade 5, co-operating with the groove 2, willhave severed the sheets, leaving the freshly-severed ends of the websimpaled upon the other set of pins 3, and the operation will berepeated. After passing the rolls 14, the sheets will emerge in thecondition shown in Fig. 25,and will then pass into the control of thetapes 7 and be conveyed to the fly 53, and by it piled upon the belts 54in the usual manner. The mechanism may also be provided with a countingmechanism, 13, similar to that described in my prior Letters Patent, No.331,282, which will operate to divide the sheets intolots of any desirednumber.

By reference to Fig. 25 it will be seen that the two products,eachconsisting of a single sheet, are delivered one partially within theother. If the two webs passed between the fold-laying rolls 23 and thecylinders 45 46 in such position as to be in line with each other, thenthe two products would when they received their transverse fold befolded wholly one within the other, and if this were the case theoperation of separating the two products,which of course is necessary,would be slow and difficult; but thesheets not being wholly one withinthe other it becomes possible to separate them readily by simplygrasping the folded edges of the two sheets and drawing them apart, andthis can be done by taking the sheets in packs of twenty or more at atime. This operation of separating thesheets is also rendered mucheasier by reason of the fact that the sheets are overlapped at theirfree edges. This peculiar manner of delivering the sheets greatlysimplifies the delivery mechanism, as by this means the singletransverse cutting, folding, and associating mechanism by being veryslightly increased in length is enabled to operate upon both webs, andthus an extra mechanism of this character is avoided.

If it is desired to utilize the full capacity of the printing machine inproducing two-sheet or eight-page products, the operation may be exactlythe same,except that the web d,which in the case just described passesover the folder H, will be led around its turning-bar 47 and thencearound the roll 21, which is adjustable to secure the proper register,so as to be superimposed upon the other web, in which condition the twoassociated webs will pass over the folder G. The product in this casewill be delivered in the form shown in Fig. 26.

When it is desired to utilize the full capacity of the printingmachinein producing products consisting of four sheet or sixteen-page papers,the operation will be the same as in producing the two-sheet productjust explained, except that the rod will be hooked onto the crank-pin39, so as to render the pins 6 of the cylinder operative, and one set ofthe pins upon the cylinder 46 will be rendered inoperative by being heldretracted, as shown in Fig. 16. As the leading ends of the associatedand longitudinally-folded webs arrive at the bite of the cylinders 4546, the cam 38 will have been rocked to the position shown in Fig. 16,so as to direct the bowl of the arm 36 to the inside of the guide 37 andprotrude the pins 6, which pins will then take the leading ends of thewebs and carry them around upon the cylinder 45 until that cylinder hascompleted a revolution, when the webs will be severed by the blade 5,and, the cam 38 having by this time been rocked to the position shown inFig. 18, the bowl of the arm 36 will be directed to the outside of theguide 37, so as to retract the pins 6 and release the ends of the webs.Just before or just after this takes place the operative set of the pins3 of the cylinder 46 will take the webs and also the forward ends of thetwo sheets upon the cylinder 45' and carry the ends of both the webs andthe folded transversely together, as indicated in Fig. 19. I

To produce products consisting of one full I sheet and one half-sheet,the adjustment and operation will be the same as in producing productsconsisting of two full sheets, except that the web D will be ofthree-fourths width, so that one of the webs d will be half-width. Thewebs will then be associated and folded, as indicated at Fig. 20.

To produce products consisting of two full sheets and twohalf-sheetssuch as shown in Fig. 21the adjustment and operation will bethe same as in the case of the four sheet product, except that the web Dwill be of three-fourths width.

Products consisting of two full sheets may also be produced, as shown inFig. 22, by using a web D of half-width and operating the cylinders 4546 the same as in producing the foursheet product, or, as shown in Fig.23, by using a web D of full width, leading one of the webs d over eachlongitudinal folder and operating the cylinders 45 46 in the samemanner.

Still other variations in the size and form of the product produced maybe obtained by inordinarily-skillful mechanic if any such range ofcapacity should be desired in any particular case.

Still greater capacity and range in the size of the product may beobtained by using a supplement web in addition to the main web, and suchsupplement-web can be supplied from any supplement-printing mechanismlocated at the side of the delivery, or in any other convenientposition. When a supplement-web of one-half the widthof the main web isused, a three-sheet product can be produced by adj usting and operatingthe delivery mechanism the same as in producing the two-sheet productalready described, or a six-sheet product may be produced by adjustingand operating the mechanism the same as in producing the four-sheetproduct already described.

It is of course necessary that the pins 3 should be retracted to releasethe leading ends of the sheets as soon as the folding-blade 4 commencesto act to fold the sheets between the rolls 14. From this it resultsthat there is a time, after the sheets have been released from thepins3and before they are fully nipped by the rolls 14, that they are notunder positive control, and during this interval they. are liable toslip backward slightly upon the cylinder 46. To avoid this, the cylinder46 is provided with two or more stationary pins, 11, which are sopositioned as to impale the margins of the sheets near their rear ends,and thus prevent the sheets from slipping backward on the cylinder whenreleased by the pins 3. The pins 11 are preferably pivoted in the endsof studs 43, (see Figs. 18 and 18",) whichare screwed into the cylinderand arranged so that when not needed they can be turned down intorecesses 44, formed in the cylinder. It is also found preferable inpractice to provide the cylinder 45 with similar pins 11, arranged toimpale the rear ends of the sheets, so as to aid in holding them snuglyupon the cylinder.

The folder H may be modified considerably as to its form withoutdeparting from its essential features. For example, as shown in Figs. 7,8, and 9, the internal member of the folder, instead of being formed ofa plate, It,- the edges of which form the internal guides, 8 9, may beformed of a bar,8, arranged obliquely to form the internal guide 8,around which one-half of the web passes, and a bar or roll,

9, which joins with the end of the bar 8 and is arranged to form theinternal guide 9,around which the other half of the web passes, this barand roll being supported by rods 17, extending from the frame of themachine, the same as in the case of the plate. In the case shown the endof the bar 8 forms a bearing for the journal of the roll 9, and is soshaped as to correspond to the shape of the plate It at thecorresponding point. In this case, also, the external member of thefolder, instead of being a plate, the edge 10 of which forms theexternal turner, consists of a bar, 10, arranged obliquely across theweb in the same position occupied by the edge 10 of the plate 9. Thisbar is supported by rods 16, the same as in the case of the plate.

theinternal and external members of the folder are composed ofplates hg, the same as in the construction first described; but in this case thefolder is so arranged that the angle of the web in passing over theguiding-edge9 is considerably greater than in the first case, this insome cases will be an advantage. In this case, also, the folded webpasses beneath instead of above the roll 15. In this case, also, theplateh is provided with a spring, 12, which lies within the fold of theweb and aids in, creasing and defining the fold-line.

In some cases it will be found advantageous to provide tapes to aid inconducting the web to and over the folder H. A convenient ar rangementof tapes for this purpose is also illustrated in Figs. 10 to 12. Asshown in these figures, the tapes 24 for this purpose pass aroundpulleys 25, located above or near the roll 50, thence forward with theweb over the roll 19, thence downward along the in clined face of theplate It, and around pulleys 26, located just below the edge 9,returning around pulleys 27. Inside tapes may also be provided, if inany case it should be desirable, but such tapes will not usually benecessary. The roll 15 may be provided with a companion roll, asindicated by dotted lines in Fig. 10, and these rolls may be driven toeffect the positive feed of the web.

The forms of the folder H which have been described are regarded as thebest for the purpose; but the invention is not limited to the employmentof a folder of either of these constructions, as a longitudinal folderof any approved form may be employed without departing from theessential features of the invention.

Figs. 27, 28, and 29 illustrate an organization in which the folder H isof the same form as the folder G, but is arranged to point in theopposite direction. In this case one of the turning-bars 47 and the roll22 are extended, so as to accommodate the full width of the web.

To produce the single-sheet product shown in Fig. 25, both of the webs dare led aroi 1nd the bar .7, one web then passing around roll 21 to thefolder G, and the other around roll 22 to the folder H. The web whichpasses over the folder H is then led between the fold-laying rolls 23 ofthe folder G, as shown in Fig. 27. In other respects the operation isthe same as already described.

The form of folder H shown in Figs. 1 to 15 is not herein claimed, as itforms the subject-matter of my prior application for Letters Patent,filed October 13, 1887, N 0. 252,226.

The cutting, folding, and associating cylinders 45 46, instead of beingarranged parallel with the printing-cylinders, may, if preferred, bearranged at right angles to those cylinders. In such case, of course,the web turning and associating mechanism would have to becorrespondingly modified.

and

In producing the products shown in Figs. 19, 21, and 22 it may bedesired that the sheets or pairs of sheets which are associated afterbeing folded longitudinally should be pasted to- 1 gether along the lineof the longitudinal folds. i This, if desired, can be readily done byproviding a suitable pasting mechanism at any convenient point whichwill operate to apply sheets adjacent to the longitudinal fold-line, sothat when the two sheets or pairs of sheets are associated upon thecylinder 46 they will be united by this line of paste.
